' Beit known that l, SHUMAN M. COLE, a citizen ot' the UnitedStates ot' America, residing at` Anainosa, in the county of Jones and St-ate of Iowa, have invented a new and useful Device` for Elevating and Measuring Oils and M y invention relates to a device for elevatin'g and measuring oils and other fluids and the object ot' my improvement is to provide a device whereby oils and other fluids may be elevated and measured from a tank or vat in one operation. I attain this object by the construction, arrangement, and combination of the several partsas illustrated in the accompanying drawings, in whichl Figure 1 isa side elevation. tional elevation;

Similar letters of reference refer to Vsimilar. parts throughout the several views. A is a tank or vat containing the oil or fluid It isplaced di-V rectly beneath the loor w or on it. A is made Fig.42 is a secmade. i

C is a cylinder, made of metal or any suitable material. ltrests'inside ofthe tank A, on

the bottom-of the cylinder will be a short distanceabovethe bottom of the tank. The cylinder extends up through the top of the tank, with its cover j ust above thetank,fand provided with a neck or mouththrough'which the stem or piston-rod b passes, and on which the spring S rests and has abearing. At the bottom of the cylinder C is a valve, u, which opens upward into it. s s

D is the piston of the ,cylinder C, fit-tin g close and snug tothe sides `of the cylinder. It is the mouth m ofthe cylinder, having at its top` a handle or foot-rest. Around the top end of the piston-rod b, and between its handle and the mouth or neck m of the cylinder, is a spiral spring, S, having a bearing against the handle and the mouth, and is for the purpose of forcing the piston-rod up after being pushed down. The cylinder O is air-tight.

P is a pipe running from the lower side of nection with pipe P. This valve opens upward or inward.

E is a piston or oat in B on the lower end of the stem c, and lits snugly onthe inside of B. The stem e extends up through a vent in the top of B, and is provided with a graduated scale toindicate the quantity oi' oil or fluid drawn. olf from B. The stem e and piston or float E move freely up and down in B. Near thebottom, at the side of B, is afaucet or cock, c, for the purpose of drawing o the oil or uid from B.

The measuring-receptacle B may be round, square, or any desired shape, being air-tight, with the exception of a vent or opening in the top for the free movement of the stem e. The connecting pipe P is ot' metal or any other suitable material.

All the several parts are arranged as shown, in the drawings. s

The manner of operation is as follows: lt being desired to measure and draw oiii some of the oil`or other fluid in the tank A, the piston D being near the bottom ofthe cylinder C, having been pushed there by the operator by means of a foot-pedal or hand-lever on the end of b, the operator releasing the pressure, the spring S, which had been compressed, will force the stem b up, carryingthe piston D, and thereby creating a vacuum in the cylinder C; or a` B will force up the piston or iloatE to the top until themeasuring-receptacle Bis tilled. The

IOC

piston or float E will stop the "ent around the spindle e, thereby stopping; all possibility of more than a certain quantity being forced into B, and also preventing any slopping over of any oil, as is the case with other measures' now in use. B having been filled, the valve a will close. The party desiring to draw off any quantity places the can or pan under the faucet or cock c and opensthe same, when the oil will flow out. 1t' B is of glass, the 'amount will be indicated by the graduated scale on B. Il' of metal, the same will be indicated lby the gradnat'ed scale on e. As the oil is4 drawn oi' the lloat E Will drop, keeping on top of the oil, and the piston c lwill descend, indicating` the loss of oil by being drawn oft', or what is remaining in B. The operation thus described can be repeated as often as desired.

Having described m y in veu tion, what Iclaim as new,and desire to secure by Letters Patent,

v1. In a device for elevating` and measuring oils and other uids, the combination, With the tank A, having perforated cover, of the cylinder C, resting on supports in said receptacle, and having extended tubular neck, and provided with valve a., and piston D, having rod b, provided with spring S, said spring being held between the anged neck of cylinder C andfoot-rest of piston-rod l), substantially as shown anddescribed.

2. In a device for elevating and measuring oils and other iuids, the combination .of the tank A, having cylinder C, provided With valve a, pistou D, provided with spring-rod b, Workhaving valve af, faucet c, and float E, having graduated standard e, passing through vperforation in cover of said receptacle B, substantially as shown and described.

3. A[na device for elevating` 'and measuring oils and other fluids, the combination, with the tank A, having perforated cover, the cylinder C, supported in said tank, and having valve a, piston D, provided with rod I), having spring S Wound around its upper end, and tubular neck, forming guide for said piston-rod, ot' the measuring-receptacle B, having valve a in its bottom, piston or oat E, suitable devices for measuring its contents, and discharge-faucet c, and the pipe P, connecting cylinder C and measuring-receptacle B, all substantially as shown and described.

In testimony whereof I ax my signature in presence ot' two witnesses.
